  1. Just been having a quick peak at pleiades open cluster with my scope on a very wide feild low mag view and seen a object like a star fly through it leaving no trail and extremely fast..... Using the directional controls on my goto I followed it right across the sky for around a minute and it didn't seem to loose any sort of glow and left no trail
  2. Hello I wanted to share some recent work of M45 from 1/8/2018 Here we have the Pleiades aka Messier 45, bathing amongst the very faint golden galactic cirrus which spans across the constellation of Taurus. The dust that you see here is actually not emitting light but rather reflecting. It is partially illuminated by the bright 7 stars within the Pleiades and additionally illuminated by our milky way galaxy. I am unclear of the distinction between IFN and galactic cirrus, Galactic cirrus seems to be closer to the core of the milky way. IFN and Galactic cirrus both actually appear in IRAS and Planck thermal dust surveys. Regarding molecular structure, I have read that IFN is comprised of Polycyclic Aromatic Hydrocarbons which are essentially leftover burned up carbon remains. The IFN reflects light predominantly at 540nm up through 950nm according to Mandel Wilson. Capturing Galactic cirrus and the bluish gray dust surrounding the pleiades requires very dark skies and deep integrations of data which must be carfeully processed. I am not 100% happy with this image yet and there may be a few more renditions, but I hope you enjoy what I have presented. Equipment and image capture: Cameras: Tandem Canon DSLR Full Spectrum modded T2i Unmodded T3i Lenses: Samyang 135mm F2 on each camera Filter: T2i only, Astronomik Clip Luminance L3 Light frames: 468 Exposures:30s Iso: 1600 Darks: 70 Flats:200 Bias: pre established master Seeing was 4/5 Transparency 5/5 Temp 25f SQM 21.6 Data was Fully Claibrated, stacked and registered in Pixinsight.

  3. Multiple DeepSky Objects

  4. M45 (close up)

    From the album Deep Sky III

    An RGB image with a synthetic Lum layer. I decided to try taking a close up of M45 since I was interested in revealing the details of the nebula. I like the details and the star colours, however, I think I prefer a wider field of view. LIGHTS: R:25, G:14,B:49 x 120s, DARKS:30, FLATS:40, BIAS:100
  5. M45 (close up)

    I wasn't entirely sure how a close up of M45 would look but I was interested in seeing if I could maximise the nebula's detail. I do like the resultant detail and colours of the smaller stars but I think I prefer a wider field of view. The image is an RGB with a synthetic Lum layer and was taken with my Esprit 150. It represents about 3 hours total integration time. Alan LIGHTS: R:25, G:14,B:49 x 120s, DARKS:30, FLATS:40, BIAS:100
  6. Clear night last night (7th). Captured with ED80 and Canon 1200d (modded), 25 subs of 300 secs at 1600 iso and using an IDAS P2 LP filter all on my AVX and guided by QHY 5-II. Processed using APP and just a few tweeks in Paint Shop Pro X9. Peter
  7. 20170923 M45 Pleiades (200om)

    From the album Alt-Az / NoEQ DSO challenge

    First successful try at 1mn subs with my Alt-Az mount. This is full width frame, and cropped a little vertically for 3:2 DSLR-like ratio and avoiding some artifacts. Looking at the result I regret I didn't let the lens wide open, but I had to try closing it to check whether CA was going away (it's not). Equipment: Olympus E-PL6 with OM-Zuiko 200mm/4 at F/5.4 (ring filter step-down adapters) and TS-Didymium filter on Celestron Nexstar SLT. Capture: 12 lights (/90% keep) x 60s x 3200 ISO, 17 darks + 20 x 20s x 3200iso (for HDR mixin, in a faint tentative to reduce stars) Processing: Regim 3.4, Fotoxx 12.01+ Sky: near country 50km from Paris, no moon but otherwise poor (moisty) conditions

  8. Astronomical twilight ends 6:18pm Transparency: 4/5 to 3/5 (above average to average) Seeing: 3/5 (average) Location: Fort Collins, CO Elevation: 4997 ft. (1523 m.) Bortle 6 to 7 skies depending upon which direction you're looking. The Double Cluster is pretty clear tonight. I can see it in my binoculars as well. M31 is very clear, and in the Binoculars as well. I then try and catch M8 which is just barely above the building down the hill from me. The time is 5:40pm MST. M8 gives up it’s nebulosity only using the LP filter I use. Orion UltraBlock Narrowband LP filter. I find M20, M21, M23, M10, M24 with my telescope (8SE) and then: At 6:15 pm, I go for M22, this is a new object for me. M22 is nice and clear, with good granularity, and some individual stars using the 17mm which gives me 119x. This is usually the best globular cluster eyepiece so i leave it in there for the next object. But before I do that, I decide I’m going to find M22 with the 10x50’s using my red dot star pointer. Note: The nice 9x50 RACI finder scope I’m thinking about will not be usable in this way like the crappy little star pointer does. A telrad would be nice I suppose and certainly it's clear why people like them. I'm just looking into making my 8SE non-GOTO (because I'm clearly a star hopper at heart and really want a 16 inch minimum travel dob from Hubble Optics). We shall see if i really even need to do that since I'm actually successfully using the 8SE to teach me the sky. Since I'm taking notes and all. I actually am able to find M22 with my cheap 10x50 bino’s. Fuzzy little ball but definitely there and visible to my binoculars. Next up: M55. It’s roughly 6:27pm MST and I continued through my list. M55 is a nice bright glob tonight. I get down and peer through the star pointer and gauge which section of sky I’m looking for and stand up, put the bino’s to my eyes and with very little searching I found M55! Next was M25, not sure I found that with my binos really. Then I was at M18, M17, M16 all three were lovely. It was roughly 6:48pm by then. Because I was mainly looking for nebulosity I didn’t try these three with the 10x50’s. I’m sure i should have. I catch a glimpse of M76 when I thought I was slewing to M16 in the prior group. I thought, what a waste of battery power. I looked at it briefly, and slewed back to the object on the list, M16. Next was M11 which I then found with my 10x50’s. A nice little dusting of stars in the binoculars! Following that was M13 which gave a particularly clear view this evening. I have been looking at star charts for quite a while now, and I have something of a photographic memory (comes in handy during band practice!). So I used the star pointer to give me the section of sky. This section of sky is really hard to look at and not loose your dark adaptation. I use an eyepatch and a black t-shirt pulled over my head backwards as a hood to keep stray ground light out. But trying to find something in the sky and star hop to M13 seems really not doable to me. However, the star pointer does show me where M13 is and I find it easily between Eta and Zeta Herculis. Just southwest? Of Eta Herculis. Now, this is the cool part. Because I’ve looked so often at the Hercules constellation, I had a good idea that you just went back to Eta and then you could find M92 between Eta and Iota Herculis. Slightly more than halfway. And there it is, a short star hop after finding M13, I find M92 without the telescope helping me. From a star chart in my memory. Awesome. Emboldened by this additional object added to my list of things I’ve seen with my 10x50 binos, I went back to Cassiopeia and hunted around there using the 10x50's to look for NGC 663 and NGC 7789. I definitely see NGC 663. I find M45, Hyades, Aldebaran, I use Delta and Gamma Cas to point me towards NGC 884 and NGC 869 aka the Double Cluster. As always, it is beautiful to see. I really like the 10x50’s. Really looking forward to the 20x80’s I’m getting next. Next I aimed my 8SE towards M57. I tried to see that with my 10x50’s but couldn’t. I thought I did but couldn’t confirm it. About 7:30pm MST I slewed over to M56. This is a nice Globular. Bright, granularity, some individual stars. Very nice. I go for this one in the bino’s and there it is! At 7:39 or so, M27 was up in the 8SE and i tried for that with the 10x50’s and I do believe I found that as well! M71 right after that, and yes, I did in fact use the 10x50’s on this object and found it as well. From M71 I found the Coathanger Cluster. So there are a couple new, easy to find (i think) objects M27 and M71 between Deneb and Altair just south of the coathanger cluster. I’m sure I can do better at star hopping but this is a lot of fun making my 8SE actually teach me something. M29, the cooling tower, very nice in the scope, very not found in the bino’s. I’ve been looking for this object in the binos for a while. It’s pretty easy to know where it is, there all close to Deneb and all. It being just south and above of Gamma Cygni. But seeing the cooling tower in the 10x50’s might be impossible. Maybe the 20x80’s. I went on to M15 around 7:43 pm MST. Very bright! Wow, this is amazingly bright! I handily found this in my binos as well!. M2, M73, M72 all found first by the 8SE and then by star pointer to my binos. Right at 8:00 pm MST I saw M30 on the list. I know this is a new object. So my crazy memory tells me. So i slew to M30 and gaze upon its beauty for many minutes in the 8SE. I find it easily in my binos with the help of my telescope. Last couple objects on the list: M77 - 8:09 pm MST this is only visible by slewing the telescope and introducing motion. I did not find it with the 10x50’s. M76, which was given a glimpse earlier was not findable by my lazy, about to call it a night, eye. The temperature was 36 degrees and my hands were beginning to hurt from the cold a bit. The thought of going inside and playing guitar instead of freezing in the somewhat stout wind (6 or 7 miles per hour) is probably why I couldn’t find the little dumbbell nebula. I see one object on my list from that night I skipped. M34. It keeps getting on the list then falling off at the last minute… it’s still early in the season for that object though. Although I didn’t even stay out long enough to see Orion coming up (over the tree). I thought to myself, as I packed things up around 8:20pm MST, that was a pretty short session. But it was action packed with lots of new bino objects found! Tonight (11-14-17) the transparency is “transparent” it is supposed to be cloud free but the seeing is bad (1/5) to poor (2/5) and 20 mile an hour winds. So no star gazing with anything but Binoculars in a parka on a zero gravity chair for me tonight. I'll let you know how many of those new targets I can see tonight. Pretty sure I’ll be able to find M13 and M92. M27 and M71 will be trickier But I think I can find M30 again. I'm going outside to try in a few minutes here after I post this.
  9. This started on 10/31/17 I had set my 8SE up at around 7:00 pm Transparency: above average 4/5 Seeing: average 3/5 I viewed a number of objects with my 8SE: M31, M32, M110 was not able to see. M57, M27 are always available. M13, M92 sitting very pretty in a clearer patch of sky than usual to the west. I was early enough to catch some favorites, M8, M16, M17, M20, M21, M22, M23, and M24 I then took a break and when I came back I grabbed my binoculars, 10x50's. First I viewed Pleiades, then Hyades, then over to Mirach, Nu, Mu, and above that to M31. I couldn't see M110 or M32 in binos. I've been searching for Kembles Cascade with binoculars, which I've found with the 8SE, though you can only see two stars at a time at that magnification and narrower FOV. So I'm looking around the general vicinity below Cassiopeia, in Camelopardalis and eventually wander into Perseus and find: The Double Cluster with my binos. I slewed the 8SE over to NGC 884, and NGC 869 to confirmed that I had in fact found the double cluster in my 10x50's I finished my bino tour of the sky on the Coathanger Cluster. I have never viewed the Coathanger cluster through my telescope. Well, maybe once just like M45 and Hyades. I always use binoculars to look at these objects now. I finished the evening on M42 which I end up looking at for nearly an hour through both the binoculars and my 8SE
  10. Pleiades 2017

    While waiting for the main target to rise, sometimes I aimed the lens and camera to the Pleiades. The setup is Canon 300 F4 L and ASI1600MMC. Camera cooled to -15C, 350x60s subs at unity gain. Lens wide open and IDAS-P2 filter. And last year's shot with the DSLRs and the Tair lenses used as colour. Perhaps they could have been better processed, this is the first try while waiting for one more panel on Orion. It's very difficult to remove the light pollution due to the IFN, perhaps this could have been done better too.

  11. Pleiades (M45)

    The Pleiades (M45). This is a shot I've been wanting to do for a long time. Previous attempts were unsatisfactory because my 127 Mak has too much focal length for this object and looked straight through it and using a camera lens made unattractive spokes around the stars caused by the iris of the lens. With the 150mm Newtonian scope the framing is great and plenty of nebulosity can be captured. Also the spikes caused by the secondary mirror spider add to the image. Not perfect perhaps but definitely the best attempt so far. 44 x 75 second exposures at 400 ISO (55 minutes integration time). 46 x dark frames 38 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity and Photoshop Equipment: Sky-Watcher Explorer-150PDS Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR

  13. Cloud Covered Pleiades

    From the album The-MathMog's Images

    Taking advantage of a short break in the cloud cover. Although a thin layer is still present.
  14. M45

    From the album Deep Sky II

    My second attempt at M45 (the first attempt with my SX26C is within the album Deep Sky I). Although this is not an ideal field of view, the close up of M45 does reveal quite a lot reflection nebula structure. The galaxy at the bottom right is PGC13696. I decided to go for quite a long exposure on the L to bring out the faint dust. I would like to have captured more green and blue data. In total, about 7 hours. LIGHTS:L: 19; R:12: G:5: B:6 x 600s. BIAS: 100; DARKS:30; FLATS: 40 all at -20C.
  15. M45

    With the poor UK weather, I ran out of patience waiting for additional colour data on the green and blue channels, so here's 7 hours of M45. Although the framing is not great within this field of view, I do like the detail and the fact that I also managed to capture a faint galaxy (PGC13696 - bottom right) with a bit of colour. Alan LIGHTS: L:19; R:12;G:5;B:6 x 600s, BIAS:100; DARKS:30; FLATS: 40 all at -20C.
  16. Some time ago I managed to capture faint nebulosity around the Pleiades. But my stopped down 135 mm lens creates less than flattering diffraction spikes, which I don't like. To get rid of these, I cut an aperture mask out of black paper, which I sandwiched between the lens and a UV filter. Yesterday was an unusual clear night at my dark site, but I couldn't start imaging until about 9 pm. I managed 7 usable subs at the same settings as before, and here's a quick result, and a side by side comparison of the previous and new data. (old data was 35 x 7 miutes, new data is only 7 x 7 minutes). The mask has an aperture that stops down the lens to approximately f/5.2, while the unmasked version had the lens stopped down to f/5.6. No elaborate processing, only simple stretches applied in PixInsight. Both images are cropped to roughly the same field of view. Without mask With mask

    From the album Alt-Az / NoEQ DSO challenge

    Try at piggyback on the Mak+Altaz horse. Very difficult to focus dim subjects with those modern lens, real lack of luminosity despite perfect sharpness. Also seems to totally lack color (unless it's saturation). Capture: 1 x 30s x 2000iso, Olympus E-PM1 with M.Zuiko 40-150:4-5.6 at 120mm:7.1 on Celestron 127MAK on Nexstar SLT tracking Alt-Az.

  22. I forgot to share this one last month. Between travel for business and brutally cold weather closing down my nearby imaging location in the mountains I have not had time to image this year. This was taken at the beginning of December and contains a very busy wide field splitting the constellations Taurus and Perseus. The better known DSO's are M45 the Pleiades reflection nebula and NGC 1499 the California emission nebula. The center of the image contains a dark nebula which I am not familiar with and the rest of the region is quite heavily laden in ISM interstellar medium dust. This image was taken with my unmodded T3i Information about this image camera: unmodded T3i ISO:1600 Exposures: 102 x 100s Darks: 5 ugh, mishap Bias:450 frame master Flats:35 Lens:SMC Pentax M* 50mm F1.7 stopped to F4 SQM: 21.1 Seeing: 3/5 Transparency:3/5 Calibrated and partially processed in Pixinsight and finished off in Photoshop CC 2017.

  23. Just looking through some rubbishy images I don't plan to use from last year (2016 :p) and saw that in this one there is an asteroid, presumably, near the little fuzzy PGC13696 just off Electra. This area is rich in these little moving chaps, but stacking the images normally removes their trails. If you have your own M45 images, it can be worth setting three or four up, one from the start of the session, one from the middle, and one at the end, stretch them, then blink between them. If there is any asteroid activity your eyes should pick up the moving white dot quite easily. The necessary details for the image are: Date: 03/12/2016 Start time: 20:50 GMT End Time: 22:28 GMT Object travelling left to right as seen in the image. I'm pretty sure there is a way to go back and ID these objects at the MPC, anyone know how? Thanks Tim
  24. Had scope out last night but seeing was rubbish due to moisture so I decided to piggyback my dSLR & capture some widefield shots. All images are taken at 14mm on my 4/3 dSLR, equiv to 28mm full frame.
